Welders goggles typically contain a dark or tinted lens (usually made of glass or polycarbonate) to protect the eyes from the bright light and harmful UV radiation produced during welding. They may also have adjustable frames, cushioning for comfort, and sometimes side shields for additional protection.
Exposure to welding UV rays can cause skin burns, eye damage, and increase the risk of developing skin cancer for welders. It is important for welders to wear proper protective gear, such as helmets and clothing, to minimize the health risks associated with welding UV rays.
The mass of a pair of science goggles can vary depending on the type and brand of goggles. Typically, science goggles weigh around 50-100 grams.
Welders need good hand-eye coordination, manual dexterity, and physical stamina to work long hours in various positions. They must also have the ability to lift heavy objects and work in confined spaces with protective gear on.
Goggles purchased "off the shelf" should not be refractive, i.e. should not have a 'focal length'. I suppose if you're a die-hard compulsive SCUBA diver, you could buy prescription goggles; then their focal length would be whatever suits your prescription. But for anything bought in a sports supply, if it has a focal length, then you're on the road to eye-strain ... take it back !
Night vision goggles detect infrared light, which is an electromagnetic wave with longer wavelengths than visible light. These goggles can amplify and convert infrared light into visible light to allow users to see in the dark.

You could use welders goggles. Or you could use a projector such as a pin hole projector.
so that they can protect their eyes from harmful electromagnetic radiations.

Plasma cutter work by emitting a very hot, very bright beam of energy. If you looking into that beam then either you are wearing a welders helmet or you will permanently damage your eyes
